Background: The prevalence of third molar pathology and problems associated with surgical extraction of impacted third molars has been extensively discussed in the literature; however, few have discussed the pathologies that can be associated with impacted third molar tooth. Aim: The aim of the current study, therefore, is to evaluate the types of associated pathologies with impacted third molars in Sub-Saharan Africans. Materials and Methods: This is a prospective study that was conducted in the Department of Oral and Maxillofacial Surgery, Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, Osun State, Nigeria, between January and March 2012. Consented patients between ages 18 and 35 years were recruited into the study. Data were analyzed using IBM SPSS Statistics for Windows Version 20 (IBM Corp., Armonk, NY, USA). Statistical significance was set at P < 0.05. Results: A total of 135 mandibular third molar extractions was carried out during the study period from 72 (53.3%) females and 63 (46.7%) males (F:M = 1.1:1). Mesioangular impaction was the most frequent spatial relation of the impacted mandibular third molar to the lower second molar tooth (70 [51.9%]), followed by distoangular impaction (29 [21.5%]). Mesioangular impaction was mostly associated with pathology (70 [51.9%]), with a statistical significant difference of P = 0.000. Pathological pocket and caries on both impacted lower third molar and lower second molar tooth accounted for the highest number of associated pathologies (37 [27.4%]). Conclusion: Caries and pathological pockets were the most common associated pathology with impacted third molar.
